It's just google-chrome.

And honestly, the last thing I want to ever see is non-ASCII URL's.

Particularly from a security person. It's a *HORRIBLE* idea with
homoglyphs, and personally I think any browser that refuses to look it
up would be doing the right thing.

But I don't think that it's the browser, actually. Even 'nslookup'
refuses to touch it with

   ** server can't find א.cc: SERVFAIL

and it seems it's literally the local dns caching (dnsmasq?)

No. It's a bad idea. Full stop. Don't do it.
